If you'd like, you can use the dnsbl stuff built into SpamAssassin. This
works great for the clients that can't afford to risk blocking legit
messages because it's on a dnsbl - instead of rejecting the connection,
you just have SA flag the message with a header that says "this is spam".
Check the mailing list archives for a message from Kelson Vibber with a
subject of 'Re: Spam Assassin Reject' for a nice filter that helps get
this set up.
